Safe and arm device for a secondary-explosive detonator

In a safe and arm device for an air deployable carrier including a submunition separable from said carrier, said safe and arm device being disposed in an electrical series circuit between a controlled switch and a secondary-explosive detonator, the improvement comprising first and second switches disposed in electrical series with each other in said electrical series circuit, said first switch having a normally open position, a closed position, a switch element adapted to actuate said first switch from said normally open position to said closed position, and first means operatively coupled to said switch element of said first switch and responsive to the presence of an air onflow against said carrier after ejection of the carrier caused by a submunition ejecting command for actuating said switch element to move said first switch from said normally open position to said closed position, said second switch having a normally open position, a closed position, and a switch arm adapted to move said second switch from said normally open position to said closed position, and second means operatively connected to said switch arm of said second switch and responsive to the separation of said submunition from said carrier for actuating said switch arm of said second switch to move said second switch from said normally open position to said closed position when the submunition separates from said carrier, whereby said closed first and second switches electrically connect said controlled switch to said secondary explosive detonator.
